Advantage is supposed to be under exceptional circumstances. I could see it leading to advantage-spamming.
I've seen this said a lot, and by a lot of different people (so not picking on you specifically, Redhammer), but I'm curious:
Where did this idea come from?
The rules simply do not say, that Advantage should be reserved for
exceptional circumstances. In fact, the DMG characterizes it as being used quite commonly - essentially any time a DM might feel there is a situation or factor that would impose Advantage (or Disadvantage). The prime example given is a Wizard running down a hallway with a couple of ogres lying in wait.
Hardly exceptional or extraordinary.
The purpose of Advantage/Disadvantage, design-wise, was to simplify the game and get away from having to track the plethora of numerical +/- bonuses/penalties.
That's it.
Nowhere in the rules does it say it's reserved for rare, grand, outstanding situations. I also don't recall this being presented in conversations by the designers, in errata, clarifications, or anywhere else.
Inspiration is supposed to be used for exceptional things, but the same is not said for simple Advantage.
I can understand not wanting to see the game spammed with Advantage - though I see no current threat of that happening, even with some of the ideas presented for the Warlord - but treating Advantage as this rare, special thing meant to be used sparely - that's not the guidance the rules give.
Where is this idea coming from?
